While this is correct according to ANSI C, I prefer
to do:

  while( fread(&c, 1, 1, f) > 0 )
    printf("%c", c);

just in case it returns a negative value (some Unix
systems have done that to me in the past).  Defensive
programming.  OK, paranoid programming <g>...

(I fail to see, however, why using fread is any better
than using getc; it's a lot less efficient for a single
character in most implementations...)
